METHOD FOR COMPLEX PROCESSING NATURAL GAS FOR OBTAINING FRESH WATER AND FUEL AND DEVICE FOR ITS REALIZATION Russian patent published in 2006 - IPC C07C1/04 C02F9/14 

FIELD: petroleum chemistry, chemical technology.

SUBSTANCE: method involves carrying out the preparing synthesis gas by the gaseous oxidative conversion of natural gas with air oxygen, catalytic conversion of synthesis gas to a catalyzate followed by its cooling and separating and feeding a liquid phase into reactor for synthesis of gasoline. For aim reducing the cost of manufacturing catalytic preparing methanol is carried out in the synthesis reactor wherein methanol is fed into reactor for preparing high-octane components of gasoline that are stabilized and separated for liquid components and fatty gas that is fed into reactor for preparing oligomer-gasoline. Then liquid components from reactors wherein high-octane components of gasoline and oligomer-gasoline are prepared and then combined, and the mixture is stabilized. Water formed in all synthesis reactions after separating is removed separately, combined and fed to the fresh water preparing block and formed nitrogen is fed for storage with partial using in technological cycle and in storage of synthetic fuel. The unreacted depleted synthesis gas from block wherein methanol is prepared is used for feeding methanol into reactor sprayers for preparing high-octane component of gasoline, and unreacted gases from reactor for preparing oligomer-gasoline are fed into generator for synthesis gas. Also, invention claims the device for realization of the method. The device consists of blocks for preparing synthesis gas, catalytic conversion of synthesis gas to catalyzate and preparing gasoline and made of two separate reactors for preparing high-octane additive of gasoline and oligomer-gasoline. The device is fitted additionally by block for preparing fresh water and nitrogen collector. The reactor sprayers are connected with intermediate capacity for collection of methanol and with reactor for synthesis of methanol and block for preparing methanol, and reactor for preparing oligomer-gasoline is connected pneumatically with block for preparing synthesis gas. Invention provides the development of method for the combined preparing the fuel and fresh water.

EFFECT: improved preparing method.
